INK FOR PRINTING ON CLOTH.

i2 0 niag macaw Y Befi't known that I, C s rAwTINE J. BUL- LINGER, a citizen of the 'En te'd States, residing at Berwyn, in the county of Cook and State of Illinois, have invented a certain new and useful Ink for Printing on Cloth, of which the following is a specification.

The object of this'invention is to provide an ink suitable for printing directly upon cloth,

as for instance in machines for marking the yards and fractions thereof on the border or selvage of the cloth which is reasonably permanent under ordinary conditions of handling of the cloth. This ink must be capable of being either brushed off or washed off from the cloth before the cloth is actually used. That is, it should be after drying, somewhat friable in its position on the cloth. The ink must not contain any material particularlyoflaygreasy or oily nature which can, in anyway, he injurious to thelcloth and theinik itself 'must be such that it will not be alfectetlibygasolene or a similar cleaning agent so thatthe cloth bearing the printed marks thereon can be cleaned without removing the printed marks therefrom.

The invention consists invan ink capable "of carrying out the foregoing objects Which can be very economicallymanufactured and in other featuresand'details which will be hereinafter fully described and claimed.

In order to produceithe desired. printing effect upon the cloth, it is necessary that a body material which will not grease or otherwise stain the cloth be used, the same being held together by an adhesive material which will also serve the purpose of causing the ink to temporarily, at least, adhere to the cloth. If the adhesive material is not of the proper consistency so that it will dry with just sufficient rapidity so that While it can be readily apnlied to the cloth yet offsetting is prevented, it is necessary to apply some material which will regulate the drying quality of the adhesive material, and if there is any danger of the adhesive material detmiorating, it is necessary to apply a preservative. l/Vhere the color of the miX- ture of the ingredients having the foregoing characteristics, is substantially the same as that of the material to be marked, the coloring agent must be applied to the mixture; otherwise it maV be omitted.

My compound consists therefore of a pigment and a water soluble vehicle for carry- Specification of Letters Patent. Application filed February 1, i915.

mg said pigment. The vehicle must not be soluble in hydrocarbons, and 1t mustbe present in such small quantity,- that after the evaporation of Water thepigment-will be held to the cloth in a more or less crumbly or friable condition, so that it can be worn or brushed off, or even washed off, if necessary, like the marks of soa1 )stone,. which a tailor makes on material before he cuts it out. These marks are completely removable bybrushing. The marks that I put on are a little more resistant than these, since they must' stay on the cloth often for some months and must standsome little wear.

The proportions of pigment or coloring matter and body giving material, binding agent, and of water, must'be such that the material which I call an ink when applied to the surface of a napped cloth, for instance, will adhere to the'outside part and become entangled with the veryoutermost fibers, but will not sink into the clothto anv great extent, and cannot therefore be found deep in the meshes of the'cloth. I

I In the specific embodiment of the invention in its preferred form, and where used upon cloth differing in color from the natural color of the ink, the ink of this inventon consists in a body portion of a powdered white material easily carried in suspension by the water and adhesive, such, for instance, as slaked lime, chalk, or French zinc white, the latter being preferred. This body portion is rendered adhesive by the addition of a suitable adhesive material soluble in Water such for instance as glue, regulated in adhesiveness by the addition of a small quantity of glycerin and preserved by a suitable preservative agent sueh for instance as thymol, both soluble in Water. The composition found to work thoroughly satisfactorily consists of a quarter of an ounce of White gelatin glue, dissolved in nineteen ounces of hot Water with Which is thoroughly added and mixed thirteen ounces of French zinc white, three quarters of an ounce of glycerin and four grains of thymol. For some reason, apparently the fact that the ink is mixed with Water, it is an actual fact that the resulting'printed mark is unaffected by gasolene applied tothe cloth.

Of course, if any oily or greasy'vehicle were used in the present connection, gasolene, or any other hydrocarbon used as a cleansing agent, in case the fabric should get spotted, would have a solvent effect, and would carry off or spread the marks. The gelatinous \'e-- hicle which 1 use is pi'acti-ally unaffected by any of the usual hydrocarbon cleansing agents. I

In order that the ink may be satisfactory The glycelrin, while diminishing the binding qualities of the gelatin to some extent, prevents 1t from-becoming too hard and brittle, and the inlgf-tlierefore, after the stamping 1S done, fioinbecon'ung too easily broken and removed-i The thymol is an antiseptic for whichother antiseptics might be substituted. It is not always needed.

The resulting mixture is sufficiently fluid so that it can be poured out of a bot'tle and used in fluid condition in the devices for feeding the ink rollers of a press-or upon a pad of a hand stand. As stated, this. mixture is satisfactory where its color differs sufiiciently from that of the color of the goods to be printed, so that the printed marks can be readily distinguished. When the colors of the ink and the goods" to be stamped are too near alike, a coloring age'nt, soluble in water, say an ounce of chrome yellow is added when the ink is to be used upon woolen goods; when, on the other hand, the ink is to be used upon silk, a similar or suit- .able quantity of a dry earth color, soluble in water, low.

Having thus described my invention, what I claim as new-and desire to secure by Letters Patent, is:

1. An ink for harmless printing up'on cloth in characters easily removable by brushing or by water washing. but resistant to hydrocarbon cleansingfluids, which is used in place of the chrome yelcomprises a gelatinous vehicle, a pigmentary powder., and water, the proportions being such that the ink will attach itself to the surface of cloth, without spreading, and

will dry to a friable, but slightly adhesive comprises a gelatinous vehicle. asoftening medium, a pigmentary powder, and watr, the proportions being such that-the inkwill attach itself to the surface of cloth, without spreadin and will dry to a friable, but slightly adhesive coating. v

3. An ink-for harmless printing upon cloth in characters easily removable by brushing or by water washing. but resistant to hydrocarbon cleansing fluids, which comprises gelatin, glycerin, a pigment, and water. the proportions being such that the ink will attach itself to the surface of cloth, without spreading. a nd-will dry toafriable, but slightly adhesive coating.

4. An ink for harmless printing upon cloth in characters easily removable by brushing or by water washing, but resistant to hydrocarbon cleansing fluids, which consists of gelatin glue, 9,- 07.., water, 19 oz., zinc white, 13 oz.. glycerin. o'l.., thymol. t grams, the proportions being such that the ink will attach itself to the surface of cloth, without spreading. and will dry to a friable, but slightly adhesive coating.
